Ga2Te3由于阳离子和阴离子之间的价错配而包含结构空位，并且这些空位以约3.5纳米的间隔形成规则排列的二维（2D）平面。很可能是由于空位平面的有效声子散射，Ga2Te3表现出意想不到的低热导率（κ）。在本研究中，二维空位平面的周期性对Ga 2 Te 3的κ的影响进行了研究。（© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
Ga2Te3 contains structural vacancies due to the valence mismatch between the cation and anion, and these vacancies make regularly arranged two‐dimensional (2D) planes with approximately 3.5‐nanometer intervals. Most likely due to the effective phonon scattering by the vacancy planes, Ga2Te3 exhibits an unexpectedly low thermal conductivity (κ). In the present study, the effect of the periodicity of the 2D vacancy planes on the κ of Ga2Te3 was investigated. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
